What is PAT tester calibration?
PAT testers are used to check the electrical safety of portable appliances, helping duty holders ensure that workers, tenants, and the public are protected from potential electric shocks. Calibration involves comparing a PAT tester’s accuracy against a higher standard measurement to confirm it is correctly detecting electrical faults.
Why is regular calibration of PAT testers important?
PAT testers play a critical role in health and safety compliance, as inaccurate readings could result in faulty electrical appliances being passed as safe. Regular calibration ensures the tester is operating within specification, reducing the risk of electric shock or injury caused by undetected faults.
Can PAT testers be calibrated on-site?
Yes, Calibrationhouse provides on-site calibration services across the UK, allowing businesses to maintain compliance with minimal disruption. Alternatively, PAT testers can be sent to our Durham-based laboratory for calibration.
Does Calibrationhouse offer UKAS calibration for PAT testers?
Yes, UKAS-accredited calibration is available for all makes and models of PAT testers. Our calibration process uses high-accuracy resistance standards, ensuring reliable and consistent performance in line with industry regulations.
How often should PAT testers be calibrated?
Calibrationhouse recommends annual calibration for all PAT testers. Equipment used more frequently may require calibration more than once a year to maintain accuracy. Our team can advise on the best schedule to keep your PAT tester working within industry-recognised standards.
